A Convoluted Day!






Spent the last few days attending the LSA course and then tending to family business, primarily federal income taxes.

I say convoluted because I performed some of the steps in the finishing kit and then continued with the fuselage kit.

This afternoon I deburred the F-1202B Panel Base and attached the nutplates on the aft flange. Was ready to install it but remembered a few posts on the VAF forums.

Per Jim Cone's post on the VAF forums, he indicated he had to lower the rudder pedals about 3/8" to allow the BNC connectors for the two antenna coaxial cables to pass above the rudder pedal torque tubes. Because it is far easier to lower the rudder pedals without the panel base being installed and because I received the finishing kit a week ago, I lowered the rudder pedals and installed the two coaxial cables. Still took a bit. If you wait, you will be on your back inside the fuselage.

Also to pass the coaxial cables aft, the large SB750-10 bushings in the bulkheads have to be removed. Only way to remove them is to slit them with an Exacto knife and pull them out. The plans indicate that this may be necessary. I'll try to find where they were installed in the blog and make a note for the future builders not to install them.

Then saw a post from John Bender. At this time there are 4 nutplate attach points on the horizontal portion of panel base that do NOT have nutplates attached to them. One of them is an obvious error in the plans. At this time I do not know if nutplates are required in the other 3 locations. The most forward location is used to clamp the brake lines per Page 32-02 of the finishing kit. A K1000-3 nutplate is required here because an AN3-4A bolt is used to attach the clamp for the brake line tubing. I installed the nutplate and clamped the brake lines loosely per Page 32-03.

Then installed the panel base. The longeron to panel base match was perfect. Match drilled the longeron to the panel base.

DO not install any of the bushings per page 29-04 of the plans. All will have to be removed and slit to allow the cables to pass. Install them after all of the cables are installed.

Like I said, a convoluted day!
